A structured light system for three-dimensional shape measurement with single camera has the shortcoming of camera occlusion. To alleviate this problem, this paper introduces a structured light system with dual cameras for three-dimensional shape measurement. We discuss 1 system description, 2 system calibration, 3 three-dimensional data registration using the iterative closest-point ICP algorithm, and 4 three-dimensional data merging using holoimage. The principle of the system is introduced, and experiments are presented to verify its performance.
